Manufacture of molds - one of the key moments when casting plastmass.Professionalu this is obvious, but customers of polymer products do not always possess the knowledge necessary to evaluate the quality of manufacture of molds and understand its importance. Meanwhile, it is mold determines the appearance of the product and its performance. Manufacture of molds is one of the initial stages of work on plastic products. We draw a simple analogy: in order to bake a cake of some form, we use a special dish from the drawings, ribbed edges, and other delights. With the weight of the polymer is the same - solidify in a special capacity, it acquires the desired appearance.
But for this, and to manufacture molds - it is there and is molding plastic products. Despite its apparent simplicity, making mold requires detailed mathematical calculations and accuracy. Firstly, it is dictated by the need to observe the relation between the degree of heating the material, the volume of products, especially those used polymer, the appointment of the future product. In other words, the manufacture of molds should ensure optimal filling of the cavity and hardening the polymer. Secondly, the smallest defects in the manufacture of molds, immediately affect the appearance of the product, because the molten plastic repeats all the twists and bumps, are available in the mold.
Only a carefully designed, polished and tested mold can provide high quality products. Model molding is performed based on a sketch the product and its expected performance. Typically used three-dimensional modeling, a detailed mathematical calculation, and only then begins production of composite parts. But even the best producer would not say that mold is ready for use immediately after it was made. Before a trial is necessary to casting plastics. If the product proves to be defective, the mold will go to completion. The last stage of testing is the serial test, which verified the absence of defects have a whole lot of products.
